Support for multiple configuration files for raw data types and extended properties

[Nicklas Nordborg]

The raw-data-types.xml and extended-properties.xml files are getting larger and larger. This may pose a problem when an admin needs to add new raw data types or reporter annotations. There is no room for mistakes. It would be better if the configuration files could be split into multiple files. For example, one for each raw data type. This would also make it easier to distribute plug-in packages which require new raw data types. Configuration files that are distributed with the plug-in can then simply be copied to the configurations directory instead of having to copy and paste into the main configuration files.
